Biofuel cell tech powers radio with human sweat

Can we have sweat-powered wearables in future? The answer is yes. Researchers at the University of California, San Diego, have used only human sweat to keep a radio running for two days.

In the experiment, the researchers shaped biofuel cells into a soft patch and slapped it on human skin, allowing the system to feed off sweat to generate power, notes Press Reader.

The researchers intend to go a step further by using the technology to monitor human health through sweat-powered wearable sensors that will directly relay the data to smartphones, writes New Scientist.
